About the Weighted GPA Calculator
This weighted GPA calculator shows both numbers colleges see on a high school transcript. The unweighted GPA uses the standard 4.0 scale for every class; the weighted GPA adds a bonus for harder courses — typically +0.5 for honors and +1.0 for AP, IB and dual-enrollment classes — so an A in AP Calculus counts as a 5.0.
Pick a grade, a course level and the credits for up to six classes (a full-year class is usually 1 credit, a semester class 0.5). The boosts are editable because high schools differ: some add only +0.5 for AP, some cap weighted GPA at 5.0, and many give no bonus for a failing grade, which this calculator also follows.
Use it to check class rank implications, compare course schedules before registration, or translate your GPA for college applications. Many colleges recalculate GPA with their own rules, so treat the weighted figure as your school’s view rather than a universal number.
With the default inputs, the weighted gpa is 4.18. Change any value above to recalculate instantly.
How to use the weighted gpa calculator
- 1Pick the letter grade for each class.
- 2Set the level: regular, honors, AP, IB or dual enrollment.
- 3Enter credits (1 for full-year, 0.5 for semester classes).
- 4Adjust the honors and AP boosts if your school uses different values.
- 5Compare your weighted and unweighted GPA.
Formula and method
Each letter grade is converted to points on the 4.0 scale (A = 4.0, A− = 3.7, B+ = 3.3 … F = 0). The unweighted GPA is the credit-weighted average of those points. For the weighted GPA, a level bonus b is added to each course’s points before averaging: by default +0.5 for honors and +1.0 for AP, IB and dual-enrollment classes.
No bonus is added to an F, which matches most school policies. A+ counts as 4.0 here because most high schools cap the unweighted scale at 4.0. Credits let semester (0.5) and full-year (1.0) classes count proportionally.

Worked examples
Junior with two AP and two honors classes
Unweighted points × credits: 3.7 + 3.3 + 4.0 + 3.0 + 4.0 + 2.0 (half-credit A) = 20 over 5.5 credits = 3.64. Adding +0.5 to the two honors classes and +1.0 to the two AP classes raises the total to 23, so the weighted GPA is 23 ÷ 5.5 = 4.18.
All regular classes
With no honors or AP classes there is no bonus, so the weighted and unweighted GPA are identical at 20 ÷ 5.5 = 3.64.
School with a +0.5 AP boost
Unweighted: 4.0 + 3.7 + 3.3 + 3.0 = 14 over 4 credits = 3.50. Three AP/IB classes each get +0.5, adding 1.5 points: 15.5 ÷ 4 = 3.875 weighted.
Frequently asked questions
What is the difference between weighted and unweighted GPA?+
Unweighted GPA treats every class equally on a 4.0 scale. Weighted GPA adds extra points for harder classes, usually +0.5 for honors and +1.0 for AP or IB, so it can go above 4.0.
Is a 4.0 weighted GPA good?+
It depends on your course load. A 4.0 weighted with many AP classes might be a 3.5 unweighted; colleges look at both the GPA and the rigor of the courses you chose.
Do colleges use weighted or unweighted GPA?+
Many colleges recalculate GPA using their own method, often unweighted core academic courses, then consider course rigor separately. Report the figures your school’s transcript shows.
How much does an AP class add to GPA?+
Most high schools add 1.0 point, making an A worth 5.0 and a B worth 4.0. Some add only 0.5, and a few cap bonus points or give none for grades below C.
What is the highest weighted GPA possible?+
With a +1.0 boost the maximum is usually 5.0 (straight A’s in all AP/IB classes). Schools that use other scales can report higher numbers, such as 5.3 or on a 100-point scale.
